Public bug reported:
OVN has been changed to use OF15 see [1]
Because of that, devstack configuration scripts must be updated to stop using
the hard coded Openflow13
protocol. Still, we should make this backwards compatible so it remains working
on potentially older
versions of OVN.
The error you observe in this situation looks like this:
tail -F /opt/stack/logs/ovs-vswitchd.log
2020-05-06T21:04:31.488Z|00482|vconn|WARN|unix#341: version negotiation failed
(we support version 0x04, peer support
s version 0x06)
To work around this issue on devstack, set the protocol and restart
vswitchd service:
systemctl restart devstack@ovs-vswitchd.service
